  2. Spare Booster RF Cavity • Cavity assembly was on hold for several weeks due to safety concerns (grinding on copper) • Resume welding on 9-29 • Vendor having problems brazing ceramics, will use older ones on hand • Best case estimate, end of October • Realistically, hope to have before the holidays…

  3. Spare Booster RF Cavity • Cavity testing • Temperature spike on wide-bore cavity due to bad contact in the tuner stem. Did not flag at normal operating parameters! • Begs question??? “Acceptable” may no longer work! • Already know we have to re-work some cooling

  5. Booster RF Manpower and Schedule Manpower and discussion points • AD/MSD has provided two techniciansfor full-time RF/tuner work • TD is supplying one technician to help (and learn) build tuners • All three technicians are in training • Current MSD schedule (D. Augustine) is estimating about 5 weeks (25 days) to remove/rebuild/re-install one cavity • Not counting in schedule 10 tuners from TD budgeted for FY12. If available, these would help.
